He worked on Species-at-Risk remediation around Ojibway Park as part of the Windsor Essex Parkway Project.^[2]

Kusmierczyk was born in Kraśnik, Poland, the son of Richard Kusmierczyk.^[3][4] His family arrived in Canada in 1983 as political refugees after his father was imprisoned as a member of the Solidarity movement, which opposed the communist dictatorship and established the first free and independent trade union in communist Eastern Europe. They immediately settled in Windsor where his father worked as an engineer in the automotive industry.^[5]

In the 2025 Canadian federal election, he was unseated in Windsor—Tecumseh—Lakeshore by Conservative candidate Kathy Borrelli.^[6] After an initial Elections Canada validation reduced the loss from 233 votes to 77 – 7 short of the automatic 1/1000 votes cast judicial recount threshold – Kusmiercyk sought and obtained an order for such a recount to be held.^[7] On May 23, the recount concluded, affirming Borrelli's victory, but reducing the margin of victory to four votes.^[8]
